YVES DAVY, OF OPELOUSAS, LOUISIANA.

BRICK-MACHINE.

Specification of Application filed May 27,

To all whom it may concern.

Be it known that Yves DAVY, a citizen of the United States of America,residing at 0 elousas, in the parish of St. Landry and btate ofLouisiana, has invented new and useful Improvements in Brick-Machines,of which the following is a specification.

The object of the invention is to provide a simple and efiicient deviceadapted for use in forming bricks or building blocks by hand asdistinguished from the machines which are used for forming the same inlarger quantities, and more especially the object in view is to providea device adapted for hand manipulation by which uniformity of theproduct may be secured with the minimum effort upon the part of theoperator and with these objects in view the invention consists in aconstruction and combination of parts of which a preferred embodiment isshown in the accompanying drawings, wherein:-

Figure l is a side view of-the same with the parts arranged in theposition which they assume just prior to the advancement of the followerfor expelling the molded brick blanks from the form.

Fig. 2 is a detail view in perspective of the follower.

Fig. 3 is a similar view of the form.

Fig. 4 is a transverse sectional view of the parts in the position inwhich they are illustrated in Fig. 1.

The device consists essentially of the form member 10 which may beprovided with any suitable or desired number of compartments 11 whichare open top and bottom for the reception of the clay or other plasticmaterial of which the product or bricks are to be formed and a. followermember 12 which is of a construction complemental of the forming memberand is adapted to be moved relatively to the latter after material hasbeen molded in the compartments of the form to expel the blanks from thecompartments under such conditions as to leave them exposed at theirsurfaces for drying and subsequent baking.

In the construction illustrated the form consists of the side walls 13connected by transverse webs ll to form compartments 11 of thedimensions desired for the bricks or building blocks, said walls beingextended beyond the terminal webs to form 1920. Serial No. 334,576.

ears 15 connected transversely by rounds 16 constituting handles orclips.

The follower consists of a plate 17 to which are attached terminal ears18 adapted for sliding engagement with the exterior surfaces of theterminal webs 14: of the form member as indicated in Fig. 1, andplungers 19 corresponding in number and dimensions with the compartmentsll of the form member and consisting of folded plates secured to thebody plate 17 and spaced apart at their adjacent edges to form intervals20 of a width sufficient to receive the intermediate webs 14 to the endthat when the follower member is disposed in relation to the form memberas indicated in Fig. l and is held in a fixed position with the plungers19 upon the surfaces of the clay contents of the chambers 11 and theform member is raised relatively to the follower until the upper edgesof the walls 13 and webs 14 are in contact with the under surface of theplate 17 the blanks which have been molded in the chambers of the formmember will be left in proper position and in spaced relation upon apallet or other surface indicated at 21 to permit of their direction andtransportation to the oven for baking. The plungers are preferably of adepth to project from a plain of the plate 17 which corresponds with thedepth of the chamber or compartment 11 of the form member as will beobvious by reference to Fig. 4 and the extremities of the carrying plate17 preferably project beyond the plains of the guide ears 18 to adistance sufficient to form clips which may be engaged by the hands ofthe operator as the handles or clips 16 are en gaged, to cause therelative movement of the members necessary to expel the molded clay fromthe compartments or chambers of the form member.

What is claimed is:

1. A brick making device comprising complemental form and followermembers, the form member being provided with a series of moldingchambers and consisting of parallel side walls and transversely spanningterminal and intermediate webs connecting the side walls, transverseclip rounds connecting the extremities of the side walls beyond theterminal webs, the follower member having depending guide ears adaptedfor sliding engagement with the exterior surface of the terminal webs ofthe form members,

and a series of intermediate plungers terminally spaced apart and fromsaid guide ears to form intervals for the reception respectively of saidterminal and intermediate webs, the said guide ears being of a, heightequal to twice the height of the form member to dispose the plungers inspaced relation to a pallet for the purpose specified.

2. A hand brick forming device consist- 10 ing of complemental form andfollower members of which the form member is of compartmentelconstruction and open at its top and bottom, the follower members hav- 7ing a series of plungers disposed for insertion in the compartments ofthe form memher and dimensioned with respect thereto, the followermember being provided with depending terminal ears of a lengthsufficient to dispose the plunger members a distence above the pelletequal to the height of the form member for the purpose specified.

In testimony whereof he affixes his signature.
